Cervical vertebra moving angle measuring instrument

Abstract

The invention discloses a cervical vertebra moving angle measuring instrument, which is formed by a support and drive device, a hemispheric angle measurer and a sliding chair. According to the cervical vertebra moving angle measuring instrument, a patient sits on the sliding chair, the sliding chair is driven through a driver shaft so as to move toward a direction of a hollow hemispheroid, and a probe of a hat worn on a head part of the patient corresponds to a probe receiver when the patient stops; a drive support drives the hollow hemispheroid to move up and down on a positioning guide rod so as to adjust a central axis of the hemispheroid and enable the hemispheroid to fit to a probe on a shoulder positioning device; a waist part of the patient is fixed between two waist part plates, so that a body of the patient is prevented from moving; and when motion ranges of forward bending, rear protraction, left-handed rotation, right-handed rotation, left side bending and right side bending of a cervical vertebra of the patient are measured, the scales, corresponding to the probe at the front side of the hat of the patient, on the hemispheroid can be reflected on a display screen, and the motion range of the cervical vertebra of the patient can be obtained through recording data of the display screen only, so that the cervical vertebra moving angle measuring instrument is convenient to operate, the workload of medical personnel is reduced, and the working efficiency is improved.

Description

Technical field: [0001] The invention relates to the field of medical instruments, in particular to a cervical vertebra activity angle measuring instrument. Background technique: [0002] Neck tissue fibrosis is one of the sequelae after radiation therapy for head and neck tumors. One to two years after the patient receives radiation therapy, the fibrosis of the neck muscle group will lead to neck sclerosis and limited neck movement, which will affect the life of the patient. In order to understand the occurrence of cervical fibrosis in patients undergoing head and neck radiotherapy, evaluate the effect of rehabilitation exercise for patients, and carry out related research with cervical fibrosis as the observation index, an objective and measurable index is required. To measure the degree of cervical fibrosis; among them, the range of motion of the cervical spine is one of the objective, economical and convenient indicators to reflect the degree of fibrosis of the neck; the...

[0002] Neck tissue fibrosis is one of the sequelae after radiation therapy for head and neck tumors. One to two years after the patient receives radiation therapy, the fibrosis of the neck muscle group will lead to neck sclerosis and limited neck movement, which will affect the life of the patient. In order to understand the occurrence of cervical fibrosis in patients undergoing head and neck radiotherapy, evaluate the effect of rehabilitation exercise for patients, and carry out related research with cervical fibrosis as the observation index, an objective and measurable index is required. To measure the degree of cervical fibrosis; among them, the range of motion of the cervical spine is one of the objective, economical and convenient indicators to reflect the degree of fibrosis of the neck; the range of motion of the cervical spine includes flexion, extension, left rotation, right rotation, left rotation Flexion and right side flexion; the measuring instrument currently used to measure the range of motion of the cervical spine is the range of motion of the cervical spine, which is a medical goniometer with a fixed arm and a movable arm. It is an economical and easy-to-obtain instrument. A measuring instrument, but in the process of practice, we found that there are two difficulties that seriously affect the accuracy of the instrument: First, during the measurement process, it is difficult for the measurer to accurately grasp the positions of the axis, the fixed arm and the moving arm , leading to a large error in the measurement value; for example, when measuring the left and right rotation of the cervical spine, the axis is the top of the head, the fixed arm is the sagittal axis passing through the top of the head, and the moving arm is the connection line between the bridge of the nose and the occipital tuberosity or the top of the head, but These reference standards are all based on the subjective judgment of the measurer, which can cause a large bias; second, when the instrument is used to measure the range of motion of the cervical spine, the patient's body needs to be fixed. If the patient's body swings, the measured value will be generated. In addition, artificially fixing the patient's body can bring discomfort to the patient
